Surface Water

Groundwater

Water Table

Unsaturated Soil

Where is most groundwater located?

• Aquifers

• Springs

• Wells

• Lakes

What is the boundary that shows where soil ends and groundwater begins?

• Water Table

• Aquifer

• Recharge Zone

• Spring

Organize these options into the right categories

Groups:

(a) Well

,

(b) Spring

,

(c) Recharge Zone

,

(d) Aquifer

• place water seeps into ground

• pressurized water reaches surface

• porous rock filled with water

• can form in different rocks

• man-made

• required for healthy aquifer

• can be contaminated

• deep hole dug to reach water

• fresh not salt water

What is porosity?

• How many holes are in the rock

• The rocks ability to allow water to pass through

• How many pores are in the soil

• How deep the water table is from the surface

What is permeability?

• Rocks ability to allow water to flow through

• How many holes are in the rock

• How deep the water table is from the surface

• How permanent the rock is below the water table

what is the purpose of a watershed?

• channels rain and snowmelt to creeks and rivers

• water runs off a mountain in to the ocean

• water sheds its hydrogen atoms at it becomes water vapor

• water sheds the sides of rivers through erosion

Organize these options into the right categories

Groups:

(a) Gulf

,

(b) Wetland

,

(c) Swamp

,

(d) Estuary

• ocean with some land around it

• where a river meets the ocean

• type of wetland

• flooded forest

• land saturated with water

Organize these options into the right categories for Surface and Groundwater

Groups:

(a) Runoff Harmful

,

(b) Water Pollution

,

(c) Beneficial

,

(d) Minimize Usage

• Sewage overflow

• Rises water temps

• Fix leaks

• Recycling

• turn off while brushing teeth

• minimize usage/consumption

• Use rain barrels

• dumping trash

• oil spills

• dumping chemicals

• washes sediments into rivers

• Carry pollutants

• sewage treatment

Why are fertilizers bad for our water sources?

• They seep into the ground and contaminate ground water

• They make roots grow long and block openings for water to travel

• The animals who die from it create an overabundance of carbon dioxide

• It dries up the soil and prevents water passing through
